Everyone loves a really good co-op game. With the upcoming Lara Croft and the Guardian of Light game you will have the opportunity to play a great co-op game.

You will be able to play online and offline with both characters on screen at the same time. A downloadable game coming to the Xbox 360, PC and PlayStation 3 this Summer, you’ll be able to play as Lara Croft or Totec, her spear-throwing companion in an uneasy alliance to stop a force they both had a hand in unleashing. You’ll use guns to blast at large numbers of enemies, and you’ll work together to solve puzzles to move forward. Each challenge in the game can be tackled multiple ways, and we were shown a few solutions to the puzzles demoed for us.

The game looks great, and while we weren’t able to put our hands on it, it seemed like the controls were solid. The physics were also better than expected in a game like this; the environment reacts to your movement and in some cases can be destroyed by small explosive charges you carry and can place wherever you like.

In another interesting twist, playing single-player will cause Croft’s abilities to be changed somewhat for a more fulfilling experience, while the co-op will be more balanced for two human players working together to survive.

For $15, you get somewhere between six and ten hours of gameplay… not a bad way to spend a weekend with a friend. Going into GDC I expected this game to be something of a joke, but after this short demo, our interest is certainly much higher.
